“Life
at the Single Molecule Level”
In
a living cell, gene expression – the transcription of DNA to messenger
RNA followed by translation to protein – occurs stochastically, as a
consequence of the low copy number of DNA and mRNA molecules involved.
Can one monitor these processes in a living cell in real time? How do
cells with identical genes exhibit different phenotypes? Recent advances
in single-molecule imaging in living bacterial cells allow these questions to
be answered at the molecular level in a quantitative manner. It was found
that rare events of single molecules can have important biological
consequences.
